Interesting one. Fun stuff: I initially thought it would talk about a more technical aspect of trust and communication (e.g how do you have two services chat when you don't trust transport), and was expecting something like Byzantine faults or two generals problem, and such topics. But that made me wonder, are there any algorithms and techniques from the computer science world, related to communication in low trust, that could be retrofitted into the real world? Stuff like shared secrets, ACKs and such?
